Compared to the next best alternative, OptiMOS 5 150
V offers a breakthrough reduction in on-state resistance
R DS(on) of 25 percent in a SuperSO8 package and the
FOM g is improved by up to 29 percent over the previous
generation. Increased commutation ruggedness is
provided by the ultra-low Q rr, which is 72 percent lower
than the next best alternative in SuperSO8. An additional
outstanding feature of this product family is an improved
EMI behaviour.
TT Electronics’ zero ohm link is perfect for
compact designs
Electrically ‘invisible’ link for optional connection points on
PCBs
Woking, UK, 13 October 2016 – TT Electronics, a global
provider of engineered electronics for performance critical
applications, today launched a zero ohm link designed
for making optional connections on printed circuit board
assemblies. The LRZ0603 offers the most compact 6A
zero ohm link available in a surface mount ceramic chip
format.
With target markets in the automotive, industrial and
instrumentation sectors the link is aimed at designers of
a wide range of products including power supplies, small
motor or actuator drive systems and power management.
The zero ohm link is used for making optional connecting
points in a PCB, allowing a common PCB to be used
for multiple product variants, saving on design time and
inventory. The LRZ0603 can also be used as a crossover
to simplify – and reduce the cost of – PCB design by
reducing the number of layers needed.
The LRZ0603 features a high current rating of 6A in
SMD 0603 size (1.6mm × 0.8mm) thus reducing the PCB
area required for a high current link, enabling product
miniaturisation. It is AEC-Q200 qualified, providing the
assured reliability of an automotive grade component.
The link’s ultra-low residual resistance value is closer to
the ideal zero ohm characteristic with negligible voltage
drop and its low internal thermal impedance minimises
heating in the assembly, improving reliability and reducing
field failures.
TT Electronics’ LRZ0603 is unique among thick film on
ceramic zero ohm chips in using a copper material to
achieve low residual resistance coupled with low internal
thermal impedance. A thick film copper conductive element
is screen printed on a 96% alumina substrate resulting in
far higher current ratings for a given footprint. This new
0603 size has a similar rating to the leading competing
2512 size i.e. with approximately 16 times larger area, and
a much higher current rating than competing parts of the
same 0603 size. The LRZ0603 adds to and complements
TT Electronics’ existing LRZ product series that contains
larger sizes – see
datasheets/LRZ.pdf.
The LRZ0603’s wrap-around copper terminations have
an electroplated nickel barrier and solderable coating,
which ensures excellent ‘leach’ resistance properties and
solderability. Chips can withstand immersion in solder at
260°C for 30 seconds and are suitable for reflow or wave
soldering processes.
Factors driving the demand for this type of product are the
growth of electrical drives and actuators in industrial and
automotive markets, and the increasing offer of multiple
option product variants.
The LRZ0603 zero ohm link is available from the
following distributors: Mouser, Newark, and Farnell. For
